Question

Ethanol and water form an ideal solution (they are miscible). Both of these substances are volatile so they both obey Raoult's law. Il and ease of evaporation) 29. Which is more volatile, ethanol or water? (Think about smel 30. If you have a 1:1 mixture of ethanol and water, which has a higher vapor pressure at 25-C? 31. If you took the vapor from above the 1:1 mixture and cooled it down so that the entire vapor phase condensed, you would no longer have a 1:1 mixture. Which would you have more of, ethanol or water? 32. This problem describes the process of fractional distillation. Imagine taking the condensate from part c and heating it back to 25-C and repeating the process. After several repetitions, you would have pure ethanol! Distillation is also used aboard ships to purify water from the ocean. In this case, you don't have to do multiple cycles of evaporation and condensation.

Explanation / Answer

Which is more volatile? Ethanol or water

Ethanol is more volatile than water as it has a lower boiling point than water. It has an odour from the volatile substances its made up of. Also it is very easy to evaporate ethanol incomparision with water.
